2. Latisse, $120 for a month supply: I have a nasty habit of pulling on my lashes when I'm stressed and they've thinned considerably over the years. Unlike non-prescription lash-boosting solutions, Latisse is clinically proven so you don't have to worry about wasting your money on lackluster results.

3. Simple Cleansing Facial Wipes, $5.99: I love and use a number of different face wipes, but these are the ones I'll buy the morning after an unplanned sleepover every time.

4. I will also always, always buy Mario Badescu's Drying Lotion, $17 whenever it runs out. Aside from a good SPF, it is my desert island product. I apply it to any budding pimples every night and in the morning they're gone.

I am notoriously frugal, but counter-intuitively this means that when I do make a purchase, I will happily spend more to ensure I get the best quality, most effective product for the job. That is why every few months I grit my teeth, open my purse, wait for the moths to fly out and buy…

This pale pink gel is the softest exfoliator I have ever tried. I gently rub it on my face when I’m in the shower and my skin feels like -- I kid you not -- velvety rose petals. I use a small blob about twice a week and it lasts for months. It smells like Turkish Delight too – what more do you want?

For years I’ve worn Agent Provocateur’s classic eau de parfum, because I love everything about it from the faintly erotic powder-pink porcelain bottle to the unashamedly feminine notes of rose oil, jasmine, amber and musk. It also reminds me of my time as an AP girl (no-one folds knickers or tightens a corset better than I do.)

Rimmel is my favourite high street beauty brand and two products I repeat buy are the eyebrow pencil and kohl pencil, simply because they have good, strong pigments, go on nicely and are cheap. Enough said.

I inherited my love for Lancôme Galatéis Douceur cleansing fluid from my mum and while I’ve tried many alternatives -- fancy ones, cheapo ones, oils, wipes, you name it -- I always sheepishly return to this milk-like cleanser. It’s incredibly gentle even on my pathetically sensitive eyes and considering the amount of eye make-up I wear, that’s pretty crucial. It has my lifelong, undying devotion, even though I do occasionally fall into bed without taking off my make-up *shocker*.
